 ====Example: 3D convex hull====
+In this example **Metric Compute Volume of a Convex Hull Across Frames** is used to find the volume occupied by an individual's thorax segment between events as defined in the workspace.
+The pipeline command is as follows:
+<code>
+Metric_Compute_Volume_of_a_Convex_Hull_Across_Frames
+/SIGNAL_TYPES=TARGET
+! /SIGNAL_FOLDER=ORIGINAL
+/SIGNAL_NAMES=CLAV+STRN+CV7+T10+RSHO+LSHO
+! /RESULT_FOLDER=PROCESSED
+/RESULT_NAME=Upper_Thorax_Volume
+/NUMBER_OF_DIMENSIONS=3
+/COMPONENT_SEQUENCE=ALL
+! /REQUIRE_ALL_SIGNALS=TRUE
+! /START_FRAME=
+! /END_FRAME=
+/EVENT_SEQUENCE=EVENT1+EVENT2
+! /EXCLUDE_EVENTS=
+;
+</code>
+Here a 3 dimensional hull is used as the resulting metric will represent a 3 dimensional structure in space. The resulting metric value represents the approximate volume of the space that the upper thorax segment travels through between the events listed:
